Updating Template on Managed Personal Desktop Collection

Question

I've created a Personal Desktop collection in Server 2012 R2 and selected "Automatically Manage Virtual Desktops" so machines are created automatically using a template.  I've successfully added several Virtual Desktops to the collection,
now I need to update the template to included new patches or software.  I'm not worried about updating the existing virtual desktops because they will get the patches and software from SCCM.  However, I do want the changes to be part of the template
so they are immediately there for new virtual desktops that are added.  I haven't found a way to do this is the Server Manager or Powershell, there is an option for recreating pooled desktops, but no way that I see to use a different or newer template
on an existing Personal Desktop collection.
Do I need to manually export the template machine to the Collections IMGS folder and overwrite what is there?  Also, it doesn't make sense to delete/recreate or make a new collection for a template update.

Hi Darin,
Thank you for contacting Microsoft.
I have discussed this issue with our team. There is no supported way to do this. You would need to update the template VM and
then re-export it, both of which have to be done manually.  Some things to keep in mind though…if you just update the .vhd and you’ve changed VM Settings as well, those settings will not get picked up until the VM is re-exported. 
Best regards,
